Question
Chapter 16, Problem 5CT
Summary Introduction
To speculate: The reason why tumors of the pituitary or adrenals might disrupt monthly menstruations.
Introduction: The female reproductive system consists of reproductive organs both internal and external that are involved in reproduction and propagation of the species. The diseases and disorders of the organs of the female reproductive system show several systems. The absence of menstrual flow where the female misses three menstrual periods in a row or delay in onset of menarche row is called as amenorrhea.

Mumps is a viral infection. The primary symptom of mumps is visible swelling of the parotid gland on either side of the face. However, the virus can also infiltrate the male reproductive system, causing the testes to atrophy. Some effects include oligospermia (low sperm count), azoospermia (no sperm in semen), and asthenospermia (reduced sperm movement).
Research treatment options for reduced sperm movement. Describe one option that can be used to aid successful fertilization and explain why it helps.
Clomiphene Citrate is a fertility drug that stimulates hypothalamic secretion of Gonadotropin releasing Hormone (GnRH) in females and induces ovulation. Explain how increased GnRH with Clomiphene Citrate treatment would affect follicle maturation and ovulation in women (explain how increased GnRH would affect FSH, LH, Estrogen, and ovulation).
Chlamydia is caused by the bacteria Chlamydia trachomatis. If not treated, it can cause pelvic inflammatory disease (PID) in women and epididymitis in men. PID can cause scar tissues in the structure responsible for transporting the fertilized egg and in the tissue that is maintained by progesterone during a menstrual cycle, leading to infertility.
In the diagram above, the structures associated with PID for the effects described above are numbered

- After studying Chapter 14: “The Reproductive System,” from Medical terminology for health professions, Chapter 19: “The Reproductive System,” from Fundamentals of anatomy and physiology, and the corresponding presentations, answer the following questions: What hormones are produced by the pancreas? What do the terms hypothyroidism and hyperthyroidism mean? What are the hormones produced by the ovaries and testes? In your own words, what is a vasectomy? What do the terms multigravida, primigravida, and nulligravida mean?arrow_forwardUse the following list of reproductive hormones and structures to answer the next two questions. FSH LH Estrogen Progesterone GnRH Follicle Corpus luteum Hypothalamus Anterior pituitary Gonadotropic hormones are released by the anterior pituitary to regulate the functions of the gonads (testis in males and ovaries in females).Use the list to select a gonadotropic hormone, the structure it stimulates in the ovaries, and the main hormone that is released by that structure as a result. (There are two possible answers.) Record your answer as a 3 digit number from left to right in the same order as your answers from top to bottom of the list. ____ Gonadotropic hormone ____ Structure it acts on ____ Main hormone releasedarrow_forwardWhich of the following statements correctly describes the development of the endometrium during the menstrual cycle? Select one: A. Estrogen causes accelerated development of the endometrium during the follicle stage and then maintains the thickness of the endometrium during the luteal stage. B. Progesterone causes the relatively slow development of the endometrium during the follicle stage and accelerates the thickening of the endometrium during the luteal stage. C. Estrogen causes the relatively fast thickening of the endometrium during the follicular stage. Progesterone maintains the thickness of the endometrium during the luteal phase. D. Estrogen causes the relatively slow development of the endometrium during the follicular stage. Progesterone causes accelerated thickening of the endometrium during the luteal phase.arrow_forward
- A patient presents requesting hormonal contraception . She has been researching her options on the Web and has become confused by the large variety of OC pills available , including monophasic, multiphasic , and progesterone only . She asks how the pill prevents pregnancy and why the variety of preparations . Which of the following is the primary mechanism by which OCs prevent pregnancy ? Increasing cervical mucus viscosity Inhibiting serum follicle stimulating hormone (FSH) levels Inducing lymphocytic endometritis Inhibiting serum luteinizing hormone (LH ) levelsarrow_forwardAt the midpoint of the menstrual cycle, estrogen promotes a sudden surge of LH from the pituitary. What would be the consequence of an endocrine disrupting chemical (EDC) in the environment that mimics estrogen and is present throughout the cycle? Group of answer choices pituitary hyperplasia (cell growth) cancer development uterine contractions ovulation would not occur cervical dilationarrow_forwardPolycystic ovarian syndrome (PCOS) is an endocrine disorder. PCOS may result in irregular periods, elevated levels of male hormones, and enlarged ovaries with fluid filled sacs called cysts.Doctors may prescribe birth control pills containing only progesterone to help regulate periods and reduce symptoms.Progesterone plays an important role in the ovarian and uterine cycles. Describe the functions of progesterone during the cycle.arrow_forward

However, the virus can also infiltrate the male reproductive system, causing the testes to atrophy. Some effects include oligospermia (low sperm count), azoospermia (no sperm in semen), and asthenospermia (reduced sperm movement). Describe how intrauterine insemination can be used to aid successful fertilization and explain why it helps. Make sure that the treatment process AND how the process helps to improve fertility are clearly explained.arrow_forwardUnlike male gonadotropins, female gonadotropins are able to promote the development of a single optimal dominant follicle during most cycles with the release of a single gamete from an LH surge and then optimization of the uterine environment for implantation. To understand pathologies in this complex system, one must understand the ideal steps within the normal menstrual cycle. Which of the following statements best describes the role of FSH in menstruation? O FSH induces granulosa cell LH receptors within the dominant follicle. O FSH stimulates follicular growth only in the early preantral stage. ( ) FSH stimulates granulosa cell androgen production. O FSH increases its own receptor numbers on theca cells. O FSH induces theca cell aromatase.arrow_forwardWhich of the following statements correctly describes the development of the endometrium during the menstrual cycle? Select one: a.
